We’re betting you’ve seen more robins out your window lately than you have Andean cock-of-the-rocks—or rhinos, or maned wolves, or California condors. But why? Why are some plants and animals rare and others common? Eric Dinerstein, lead scientist and vice president of conservation science at World Wildlife Fund-US, has spent three decades pondering the causes of rarity—from physical isolation and disparate populations to habitat loss and human wars—and argues that a better scientific understanding of why some species are rare can guide us to more effective ways of protecting all types of life. As more and more species teeter on the brink, Dinerstein, author of The Kingdom of Rarities, shares stories of his treks to catch a glimpse of our rarest critters, encouraging a deep appreciation for them, their ecological importance, and the urgent need for their conservation.
